REFUSE-DESTRUCTOR.

To all whom it may concern:

Be it knownthat I Gnome WA'rsoN, a

1 subject of the King of Great Britain, and

/are suitable for camp use and isv directed thereof'a chute down which the garba casing1 of which I now propose to to certain improvements which will promote the efficiency and utility thereof.

' A destructor furnace embodying my present improvements comprises in common with previouslyknown arrangements of the same class a structure of sheet metal lined with fire brick and furnished with a chimney or flue guarded with a fire brick bridge extending across the furnace; the furnace being provided also with a charging door and removable cover and with means for removing clinker and admitting air near the bottom of the furnace.

According to my present invention a destructor furnace embodies "a device for obtaining a supply of hot water by utilizing the heat generated during the combustion .of the rubbish now generally wasted. The

structure of the furnace is such that the arched partition forms with the walls e '18., sent to be burned and an outlet flue up w ich the heat and smoke ascend to heat the water. My furnaoe,.while strong and durable, is at the same time cheap and efiective and its component parts can be easily transported and set up by unskilled labor. It embodies also a device which permits of wet rubbishbeing thrown into the furnace without endangering the extinction of the fire. The invention comprises also improved means for attaching the cover for the charging door and for supporting it when lifted from its seat. It comprises likewise constructional details in connection with the transverse bridge within the furnace which I now propose to make in the form of an arch with its ends supported on skew-back brackets secured to the furnace casing and in connection with the building up of the furnapie, the

t externa ith a bridle which will keep the plates together both during and after construction of the furnace.

Specification of Letters Patent.

Patented June 25, JlWL.

In the accompanying drawings Figure 1 is a vertical section of the apparatus including the water heater or boiler.

Fig. 2 is an elevation at right angles to Fig. l with the furnace in section and the boiler in outside view.

Fig. 3 is an outside view on a small scale of the furnace and boiler fitted with a complete system of hot water circulation. I i

Fig. 4 is a detached plan view of the cover and lifting lever of the charging hole of the furnace.

Figs. 5 and 6 are side and sectional plan views of a corner of the furnace illustrating the rod and angle pieces constituting the bridle.

a is the furnace base of the-usual type furnished with fire bars 6 and clinkering doors 0. Upon this base is erected a casing of metal sheets d lined with fire brick e between which and the casing will preferably be a layer of slag wool or similar heatresisting material." The metal sheets d are retained by tierods f and angle pieces g the fitting of which in an early stage of the erection will greatly facilitate the .building up of the furnace.

is a fire brick bridge now in the form of an arch the ends of which are supported on the skew-backs i i which consist of metal plates bolted to the casing on opposite sides which plates have inclined angular pieces arranged to underlie the end bricks of the arch. The furnace is covered with a top 9' having an aperture is for char 'ng the furnace and another 1 situated bei i This pipe m would in the ordinary way be used as a socket to support the chimney n to which the latter would be directly applied. terpose a water heater 0 between the pi e m and the chimney n so that the heat rom the furnace usually lost will be made to heat the water. The water heater is a tubular one with compartments at top and bottom, above and below the water space. The chimney n is fitted onto a tube p leading out of the top chamber. 9 is an escape pipe fitted to the water heater which is left open when it is not desired to use the boiler. for raising steam. v

The water heater or boiler may be part of a hot water circulating system an example of which is illustrated at Fig. 3. In this arnd the arch h and surmounted by a short pipe m.-

According to my invention I now 1n- Refu ' and is t placed for filling .boller 0.

1 and 2 it rangemen-t a'circulating tank r is connected by pipes to the boiler'o. This tank 1- may contain a ball cock where a constant water supply is available or it may be filled by a pump 8 from a tank 27 which is conveniently by hand. Hot water is conveniently drawn from the tank 1' tap u. '0 is a water gage fitted to the Reverting to the furnace as seen in Figs. willbe observed that there is a stool w fixed to' the furnace bars 6. This stool wis furnished with a-flat or recessed top andis provided with passages w for admitting air through it into the furnace. se thrown into the furnace through the chargin door It falls firstonto the stool w ere supported and dried. This enables very wet material to be put into the urnace without choking it and putting out the fire. The cover for thecharging hole 70 as above stated is shown in Fig. 4. This cover y is attached to a lever z the end of which is bent into aring 2 The rin a is adapted to embrace the pipe m. The tting of the ring 2 on the pipe m is such as-to by the A combined portable refuse destructor furnace and water heater comprising a chimney, an incinerating chamber, an arched partition in the upper part of said chamber arranged with respect to the walls, of the chamber to form therewith on one side a garbage chute and on the other side an outlet flue, .a grate for said chamber, a mushroom shaped air feeding stool thereon, and a water heater interposed between the outlet flue and the chimney.

In testimony whereof I have signed my name to this specification in the presence of two subscribing witnesses.
